Abstract
A front end module having reduced number of low noise amplifier (LNAs) for receiving various combinations of contiguous aggregation (CA) signals and non-CA signals having different combinations of signals aggregated therein. The FECC can include a broadband LNA and/or a band-switching LNA having at least two modes of operation. An input switch directs a received signal to one of several banks of filters. LNA switches direct the signals from the output of filters within a selected filter bank to particular LNAs. LNAs may be connected by LNA switches to filters in more than one filter bank. The proper mode of operation is selected for the band switching LNA based on the particular frequencies present in the received signal and the filters selected.
